78 — Abdullah ibn Muhammad al-Nufayli narrated to us, Waki' narrated to us, from Usamah ibn Zayd, from Ibn Kharbudh, from Umm Subayyah al-Juhaniyyah, who said: "My hand and the hand of the Messenger of Allah, peace and blessings be upon him, alternated in the ablution from a single vessel."

============================================
It was also recorded by al-Bukhari (261), Muslim (319) (41) and (321) (43) and (45) and (46), al-Tirmidhi (1851), and al-Nasa'i in al-Kubra (73) and (229) and (236) via multiple chains from A'ishah. Some of them did not mention janabah (major ritual impurity).
It is also in Musnad Ahmad (24014) and (25583), and Sahih Ibn Hibban (1108).
See also what will follow under numbers (98) and (238).

A'ishah's saying: "While we were junubun (in a state of major ritual impurity)." Al-Nawawi said in Sharh Muslim: "This follows one of the two linguistic forms of junub, namely that it can be dualized and pluralized, so one says: junub, junuban (dual), junubun (plural), and ajnab (plural). The other form is: a man junub, two men junub, men junub, and women junub, all with a single form. Allah Almighty said: {And if you are junuban} [al-Ma'idah: 6], and this latter form is the more eloquent and more famous."

It also contains evidence for the purity of the leftover water of a woman.

Al-Hafiz said in al-Fath: "Al-Dawudi used it as evidence for the permissibility of a man looking at his wife's private parts and vice versa. This is supported by what Ibn Hibban narrated (5557) via Sulayman ibn Musa, that he was asked about a man looking at his wife's private part, and he said: 'I asked 'Ata', and he said: I asked A'ishah, may Allah be pleased with her, about it, and she mentioned this hadith with its meaning.' And it is an explicit text on the matter."

(1) The hadith is authentic, and this chain is good in follow-up narrations due to Usamah ibn Zayd, who is al-Laythi. Waki' is Ibn al-Jarrah, and Ibn Kharbudh is Salim ibn Sarj.
It was also recorded by Ibn Majah (382) via the chain of Usamah ibn Zayd, with this chain. It is in Musnad Ahmad (27068).
Ahmad also recorded it (27067) via the chain of Kharijah ibn al-Harith al-Mazani, from Salim ibn Sarj, from Umm Subayyah, and this chain is authentic.
